MANUFACTURE OF WALL COPING.

SPECIFICATION forming part of Letters Patent No. 313,583, dated March10, 1885.

Application filed August 28, 1884.

- of Toronto, residing at Toronto, in the county of Jefferson and Stateof Ohio, have invented certain. new and useful Improvements in theManufacture of Wall-Coping; and I do hereby declare the following to bea full, clear, and exact description ofthe invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings,and toletters orfigures of reference marked thereon, which form a part of thisspecification.

My invention has reference to the manufac ture of wallcoping and similararticles of terracotta; and the said invention consists in the improvedmethod, hereinafter described, of molding said coping, and in theimproved molding device hereinafter fully explained.

In the accompanying drawings, forming a part of this specification,Figure l is a plan view of the improved molding apparatus employed by mein carrying out my invention, the former being removed; Fig. 2, alikeview illustrating the improved molding apparatus opened for the removalof the coping after it has been formed. Fig. 3 is a section on thedotted line 00 00, 'Fig. 1; Fig. 4, an inverted plan of the former.

Heretofore in the manufacture of coping it has been common to mold thesame in individual sections, which,when arranged for baking anddrying,would readily warp under the action of the heat. By myimprovement I overcome these defects and objections by producing at asingle molding operation two coping-sections joined together to presentan oc tagonalshaped article which can be baked and dried without dangerof warping and can, after such baking and drying action, be readilysevered to present two coping-sections.

The mold employed consists, essentially, of a base section, A, having acentral vertical core, B, the outer sides of which approximate the shapeof the article to be anolded, and are provided at each end portion witha vertical angular rib, a. Avertical recess, 1), is formed in the core Babout midway of each side, as illustrated most clearly in Figs. 1 and 2.The core B is provided centrally near each end (No model.)

with vertical perforations 0. Two jaws, O D,

are hinged together on the baseplate A, opposite one end of the core B,and the said jaws are of such shape and configuration as to conjointlyform on their inner faces the outer moldsurface for the double coping tobe formed.

As seen in Fig. 1, the said sections 0 D,when folded together, leave aspace, E, between themselves and the central core, B. The forwardportion of each section 0 D is provided with a tongue, d,which,when thesaid sections are in the position illustrated in Fig. 1, lie parallelbeneath a loop device, 6, formed on the base-plate. The tongue (I of thesection 0 has pivoted thereto a lever, F, having at its frontpivotedportion a square loop, f, which, when the two tongues are adjacent, asbefore referred to, is adapted to take over thetongue of the section Dand lock the two sections rigidly together.

G refers to the former or head of the mold, which is provided on itsunder side with a graduated series of shoulders and a bottom portion, 9,which coincides in shape with the face of the core 13, and is providedat either side of the center with lugs lnwhich are adapted to enter thevertical perforations c of the core and prevent any movement of saidhead relative to said core. Lugs 6 project laterally from the sides ofthe said former G, near each end portion thereof, and are designed toengage ears j on the sections 0 D, to hold said head in position whenthe sections 0 D are locked, andpreventthe said head from dropping outwhen the mold is inserted.

In forming the improved coping the clay is first worked roughly into thepattern indicated by in Fig. 2, which is placed over the core,

so as to rest upon and be supported by the base A of the mold, afterwhich the jaws O D are brought together andlocked with the head orformer G between them.

The closing and locking of the jaws result incompressing and forcing theclay pattern against the core B, causing a portion of the pattern toenter the recesses Z) in each side of said co're,to form the coping-rib,and additionally resulting in the angular ribs a at each end of the corepenetrating the pattern sufficient to render the finished article frailand easily severed at said points. It will, however, be

it to be passed through the various drying I finally capable of beingreadily and baking operations without liability of breakage, andfurther, to resist any tendency of becoming warped by the heat in thelatter operations.

After the article has been formed, dried, and baked, a blow or shockwill suffice to cause it to sever at its ends into two completecoping-sections.

From the foregoing it will be apparent that by the herein-describedimprovements two sections of coping or like articles of terra-cottamanufacture are readily molded together in one operation, and so formedas to permit of their drying and baking without warping, and severedinto two complete'and finished sect-ions.

vI am aware that previous to my invention it has been proposed to mold aclay pipe or cylinder and form longitudinal grooves or channels insaidpipes previous to burning the article, so that alter such burningoperation the I pipe or cylinder could be severed, so that access couldbe more readily had to the interior of said pipe.

My invention will be readily distinguished from the above, in that Imold a single article composed of two complete coping sections capableof being burned conjointly, and afterward separated, to enable each partto present a complete coping-section.

I. claim- 1. The improved method herein described of manufacturingcoping, the same consisting of molding two complete coping-sections together in a single article, drying and baking said article, and finallysevering into two com.- plete coping-sections, sustantially as setforth.

2. The improved method herein described of manufacturing coping, thesame consisting of molding two complete coping-sections to:

said reduced end portions into two complete copingsections,substantially as set forth.

3. The combination, in a mold for the manufacture of coping, of acentral core of a shape adapted at each side to form the inner portionof a coping-section and outer clampsections interiorly shaped each toform the outer portion of a coping-section, substantially as set forth.

4. The combination, in a mold for the manufacture of coping, of acore ofa shape adapted at each side to form the inner portion ofa copingsection, outer clamp-sections interiorly shaped, each to form the outerportion of a coping-section and a head or former, substantially as andfor the purpose set forth.-

5. The combination, in a mold for the man ufacture of coping, of acoreshaped to form at each. side the inner portion of acopi'ng-section, andhaving angular ribs a at each end, and outer clamp sections interiorlyshaped each to form the outer portion of a coping-section, substantiallyas set forth.

6. The combination, in a mold for themanufacture of coping, of core B,sections 0 D, hinged together at one end, shaped as (16'. scribed, anddevices for locking the free ends of said sections, in the manner andfor the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
